NUT-LOCK.

' To all whom it may concern:

Be it known that I, TRACY GEE, a citizen of the United States,"residing. at Chester,

in the county of Hill and State of Montana,

have invented certain new and useful Improvements in'Nut-Locks, of which the fol lowingis a specification, reference being had to the accompanyingdrawings.

This invention:relates to certain improvements in nutlocks and it is an object of the invention to provide a noveland. improved lock of this general type whereby the nut is provided with means engageable with the bolt for holding'thebolt against retrograde movement relative to thebolt together with an arrangement whereby said means may.

be readily rendered inoperative when it is desired to separate the nut and .bolt.

It is also an object of the invention to provideanovel and improved device of this general character including a nut engageable'with the bolt and wherein said nut has arranged? therein a member interlocking with the bolt when the nut is applied and which member and nut are capable of rela-- tive independent movement together. with means carried by the nut and coacting with themember for, holding .said nut and .member, against movement. whereby the nut is effectively held against retrograde movement about the bolt.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved nut lock whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set'forth.

The novel features of my invention-will hereinafter be definitely claimed. In order that my invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure, 1 is a view in elevation of the outer face of a nut constructed in accordance with an embodiment of my invention;

Fig. 2 is a view partly in elevation and partly in section illustrating a coacting nut and bolt constructed in accordance with my invention as herein disclosed:

taken substantially on the line 4.4 of Fig. l; Fig. 5 is a view in perspective of-the holding member or spring as herein included; Fig. 6 is a view in elevation of the inner face oftheplate coacting with a faceofthe nut'pro er; and a Fig. is a view in elevation of the interlocking annular member or washer employed in connection with the nut. As-disclosed in the accompanying drawings Sdenotes theshank of a 'bolt having the threads thereof interrupted at diametrically opposed points by a groove or channel lextending longitudinally of the shank S and open at its outer end.

N denotes a nut adapted to be threaded upon the shank S and which is provided in its inner face .with the arcuate groove 2 substantially concentric to the bore of the nut N and one end portion of the arcuate groove 2 has in communication therewith the opening 3 extending through the nut N and open at the outer face of the nut. The outer end portion of the opening 3 is enlarged as at 4.

Overlying the inner face of the nut N is a plate P having its inner face provided with a circular chamber 5 concentric tothe bore of the nut N and saidchamber 5 at its axial center is provided with an opening 6 through which the shank S of the bolt is freely directed. Snugly fitting within the chamber 5 is an annular member 7 provided on its inner face or the face thereof opposedto the nut N with an annular series of ratchet teeth 8 and with which coacts the outwardly ofiset portion 9 of the holding member or spring H. The holding member or spring H comprises an arcuate length of resilient WiIG'OfI'GqIIlSltG. gage having an end portion thereof remote from annularmember or washer-7 in one direction." The'iiiner margin of the member or "washer 7 is provided with. the inwardly directed tongues or extensions 11 each of which being seated within the groove or channel 1 when the nut N is applied to the shank S and whereby it will be perceived that when the nut N is applied to the shank 7 position. v

The end portion of the member or spring H in close proximity to the offset or tooth 9 has secured thereto the rod 12; which is a directed through the opening 3 in the nut engaged in any suitable manner to impart- N and has its outer end terminatingwithin the enlarged portion 4: of said opening." The outer. end of the rod 12 is provided with the lateral extension 14 which is adapted to be inward movement to the free end portion of the member or spring H so that the offset or tooth.9 may be disengaged from the annular member or washer 7 when it is dee I sired to remove the nut N from the shank S.

The plate P may be secured to the inner face of the nut N in any desired manner, but it is preferred that therivets 15 be em ployed and which rivets are disposed through registering openings 16 arranged at i the corners of the nut N and plate I and provided within its inner face with a slot From the foregoing description,. it is thought, to ,be obvious that a nut lock constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with,

which it may be assembled and operated and it will also'be obvious that my invention is susceptible'of some change. and modification without 'departingzfrom the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation'of the several parts herein shown in carrying I out my invention in practice except as hereinafter claimed.
